icl is a different class of bug -- icl can't fake missed interrupts at all.

commit 5f521722a2a2391d693afccdf6e12be2754382d8 (HEAD -> drm-intel-next-queued,
drm-intel/drm-intel-next-queued)
Author: Chris Wilson <chris@chris-wilson.co.uk>

    drm/i915: Missed interrupt simulation is no more, tell the world

    Using the guc, we cannot disable the user interrupt generation as we use
    it for driving submission. And from Icelake, we no longer have the
    ability to individually mask interrupt generation from each engine,
    disabling our ability to fake missed interrupts.

    In both cases, report back to userspace that the missed interrupt
    generator is no longer available.

Do you think it will also fix the ICL bug or should I file another bug?

It should do the trick. My memory of the test says that if we can't open the
file we say the engine mask is 0. However, I do have an update to the igt
pending review in case it doesn't.

We shall see what happens over the w/e and if we need to open a new bug or not.
